Q = Buyer, A = Seller:

This story happened on the morning of last Tuesday. I was dealing with replying to the customer's emails when a message popped up on WhatsApp on the website. And that's how the story between me and the customer began：

Q：Is there a corresponding RJ45 adapter plug?

Q：I saw that there are this kind of adapter heads on your website.

A：Yes, we do have this kind of adapter heads. However, we are unable to sell them to you.

Q:??

Q:Damn it! You'd better give me an explanation.

A：Because they are not compatible.

Q:What are you kidding? They are both M12 connectors with D coding, one is a male connector and the other is a female connector. Why on earth can't they be compatible? You're such a big fool!

A：Because their threads and rubber cores are embedded together. Their nuts can't be rotated, so you simply can't tighten them at all.

A：What you need is this type. The nut and the rubber core are separate. Insert it into the female connector on the other side and then turn the nut, and the connector can be tightened.

Q：Sorry, I see now. I thought that as long as the codings matched, they could be plugged into each other. Thank you.

Q:Please place a sample order for me. Once it is confirmed that it can be used, you will receive my bulk order.

A：It doesn't matter. I'm glad to be able to answer your questions. There is our email address on the website. Please send us an email and our sales team will get in touch with you for business cooperation later.
